Answer:

-4(-7/30)-3/5=1/3  

4(-1/15)+3/5=1/3

Step-by-step explanation:

1. -4x-3/5=1/3

-4x=1/3+3/5

-4x=14/15 <- divide both sides

x= -7/30

2. 4x+3/5=1/3

4x=1/3-3/5

4x= -4/15 <-divide both sides

x= -1/15

Solve following | 2x + 9 = 15
vivado [14]
  • Answer:

<em>x₁ = 3</em>

<em>x₂ = - 12</em>

  • Step-by-step explanation:

<em>Hi there ! </em>

<em>| 2x + 9 | = 15</em>

<em>1.</em>

<em>2x + 9 = 15</em>

<em>2x = 15 - 9</em>

<em>2x = 6</em>

<em>x = 6 : 2</em>

<em>x₁ = 3</em>

<em>2.</em>

<em>2x + 9 = - 15</em>

<em>2x = - 15 - 9</em>

<em>2x = - 24</em>

<em>x = - 24 : 2</em>

<em>x₂ = - 12</em>

<em>Good luck ! </em>

What's 7/12 minus 3/12 simplified? BTW ONLY IN 4TH GRADE MAKE IT CLEAR
dusya [7]
7/12 - 3/12 = 1/3
Simplify each fraction if possible.
Same denominator? YES!
7 - 3 = 4
Since they have the same denominator, you just subtract the numerators.
Then simplify 4/12
4/4= 1 12/4= 3
Answer: 1/3
Hope that helps!
